MIC834中文资料Comparator with 1.24V Ref, Open-Drain Output数据手册Microchip规格书

描述 Description

The MIC834 is a micropower, precision voltage comparator with an on-chip voltage reference.The threshold is adjusted by the choice of two external resistors. Voltage detection threshold is accurate to 1.5%.Supply current is extremely low (1.5µA, typical), making it ideal for portable applications.The MIC834 is supplied in Micrel's IttyBitty™ 5-lead SOT-23- 5 package.

特性 Features

• Optimized for PDAs, cellular telephones, pagers, and other battery-powered devices
• Input and output can be pulled up to 6V regardless of supply voltage
• High ±1.5% voltage threshold accuracy
• Built in hysteresis for noise suppression
• Extremely low 1.5µA typical supply current
• Immune to brief input transients
• 5-lead SOT-23 package

简介

MIC834属于集成电路（IC）的比较器。由制造生产的MIC834比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
